California man indicted on charge of killing daughter

This article is about a man who killed his daughter 3 years ago by shooting and suffocating his 21 year old daughter. How could you kill anyone, better yet how could you kill your daughter. I know that children can be very disrespectful and unruly at times, but what can a child do so bad as to make a parent shoot and suffocate them? This is morally and ethically wrong, and for him to hide the body for 3 years is just brutal. This man had no heart. How can a person with a heart even do anything as extreme as this? He should be tried and given life in prison for taking the life of his 21 year old daughter.
